Bei einer Bedienfläche mit mehreren Tastzonen ist jeder Tastzone ein eigener Geber zugeordnet. In an operating surface having a plurality of button zones each tactile zone is associated with its own transmitter.Das taktile Signal soll in dem Zeitraum auftreten, in dem der Bediener üblicherweise den Finger auf der Tastzone hält. The tactile signal is to occur in the period in which the operator usually keeps his finger on the tactile zone.

Der Geber kann so mit der Bedienfläche verbunden sein, dass er seine Bewegung auf die Bedienfläche überträgt. The encoder may be coupled to the control surface such that it transmits its movement to the operating surface.Er kann jedoch auch nahe bei der Bedienfläche angebracht sein, so dass er gegen die Bedienfläche klopft. However, it can also be mounted next to the control pad so that it knocks against the operating surface.

Der Geber ist dasjenige Piezokeramikelement, das auch der die Berührung der Bedienfläche oder Tastzone erfassende Sensor ist, wobei das Piezokeramikelement während der Berührung zunächst als Sensor und dann als Geber arbeitet. The encoder is that piezoceramic element, which is also the contact of the operating surface or tactile zone detecting sensor, the piezo ceramic element then functions as a transmitter during the first touch as a sensor and.Damit übernimmt das gleiche Piezokeramikelement zugleich das Auslösen der Schaltfunktinn des Berührungsschalters und die Rückmeldung. Thus the same piezoceramic element at the same time takes over the triggering of Schaltfunktinn the touch switch and the feedback.

Bei einer weiteren Ausgestaltung ist die Frequenz und/oder die Intensität (Amplitude) der Bewegung des Gebers bei Berührung unterschiedlicher Tastznnen der Bedienfläche taktil unterscheidbar ausgelegt. In another embodiment, the frequency and / or the intensity (amplitude) of the movement of the encoder is designed tactilely distinguishable to the touch different Tastznnen the operating surface.

Nachdem die Schaltung After the circuit11 11zum Zeitpunkt t1 die Sensorfunktionen abgeschaltet hat, schaltet sie mit einer gewissen Verzögerung zum Zeitpunkt t2 die Geberfunktion des Piezokeramikelements has switched off the sensor functions at the time t1, it turns with a certain delay at the time t2 the timer function of the piezoelectric ceramic element7 7aktiv, wodurch der Bediener eine taktile Rückmeldung über den Schaltvorgang erhält (vgl. Linie c in active, allowing the operator a tactile feedback of the switching operation is obtained (see FIG. line c in3 3). ).Die Geberfunktion wird von der Schaltung Donors function of the circuit11 11zum Zeitpunkt t3 abgeschaltet, der vor oder nach dem Zeitpunkt tx liegen kann. off at time t3, which may be before or after the time tx.Die Zeitdauer von t2 bis t3 ist begrenzt, so dass das Piezokeramikelement The time period from t2 to t3 is limited, so that the piezoelectric ceramic element7 7wieder bei einer nächstfolgenden Berührung der Tastzone again at a next contact of the tactile zone1 1als Sensor zur Verfügung steht. is available as a sensor.

In Weiterbildung der Erfindung kann vorgesehen sein, dass bei Berührung verschiedener Tastzonen taktil unterscheidbare Signale, beispielsweise nach Frequenz und/oder Intensität unterscheidbare Signale, erzeugt werden. In a further development of the invention it can be provided that the touch button zones of different tactile distinguishable signals, for example according to frequency and / or intensity distinguishable signals are generated.Beim Ziffernblock der üblichen PC-Tastatur trägt die Taste der Ziffer "5" eine tastbare Markierung, damit sie auch ohne Sichtkontakt erkennbar ist. Numeric keypad, the usual PC keyboard the number "5" key, carries a palpable marker so that it is visible even without visual contact.Entsprechend kann bei der vorgesehenen Einrichtung vorgesehen sein, dass bei einer Betätigung einer Taste, beispielsweise der " Accordingly, it can be provided at the intended means that an actuation of a key, such as the "5 5", des Ziffernblocks ein anderes taktiles Signal entsteht als bei der Betätigung einer der anderen Tasten des Ziffernblocks. "The number pad to another tactile signal is produced as in the operation of one of the other keys on the numeric keypad.
